Hey guys I searched a ton but couldn't find any info, I put oem e46 m3 18" wheels on my 330i and fitted a squared 225 set of tires onto the staggered wheels. It rubs a little not much and not hard.

My question is basically for tips on how to live with slight rubbing, or if there's anything i can prep/do (not fender rolling) to minimize any damage the tires gonna do on the fender. Maybe clean/coat it with something every few weeks?

I'm not gonna be driving a ton in the winter and just don't see the point of rolling if it doesn't rub 75% of the time. Unless someone can convince me otherwise.
Thanks in advance
